β‐Adrenergic Signaling Promotes Anti‐Tumor Immunity in TP53‐mutant Oral Squamous Cell Carcinoma

Advanced Science, EarlyView.
β‐adrenergic stimulation enhances anti‐tumor immunity in TP53‐deficient oral squamous cell carcinoma by inducing tumor‐derived secretion of CXCL10, which attracts and activates cytotoxic CD8+ T cells. The findings demonstrate that β‐adrenergic signaling alters tumor–immune interactions via CXCL10‐mediated paracrine activation, revealing a neuro‐immune ...

The Application of Canonical Correlation to Two-Dimensional Contingency Tables [PDF]

Tutorials in Quantitative Methods for Psychology, 2010
This paper re-introduces and demonstrates the use of Mickey’s (1970) canonical correlation method in analyzing large two-dimensional contingency tables. This method of analysis supplements the traditional analysis using the Pearson chi-square.

Global Nitrogen Deposition Promotes Carbon Sink Formation in Terrestrial Ecosystems

Advanced Science, EarlyView.
Nitrogen deposition alleviates ecosystem N limitation and enhances carbon sinks. Using 829 observations, we show 36% of deposited N is retained globally (39.15 Tg N yr−1), with distinct NHx and NOy contributions. This retention drives a terrestrial C sink of 0.88 Pg C yr−1 (25.48%), highlighting the importance of pool‐specific C:N stoichiometry ...

Enumerating contingency tables via random permanents

, 2005
Given m positive integers R=(r_i), n positive integers C=(c_j) such that sum r_i = sum c_j =N, and mn non-negative weights W=(w_{ij}), we consider the total weight T=T(R, C; W) of non-negative integer matrices (contingency tables) D=(d_{ij}) with the row

Androgen Receptor‐Induced Lactoferrin Accelerates Prostate Tumorigenesis Through Modulating Ferroptosis

Advanced Science, EarlyView.
This study demonstrates that transcription factor androgen receptor (AR) directly binds the LF promoter, driving lactoferrin overexpression to promote ferritin (FTH1/FTL) upregulation and inhibit p53‐ALOX12‐mediated ferroptosis in prostate cancer. Lactoferrin could be a new potential therapeutic target in prostate cancer.

Asymmetry Plus Association Models for Ordinal Square Contingency Tables

Journal of Statistical Theory and Applications (JSTA)
In contingency table analysis, statistical models have been used to study the linkage between variables. The independent model is used to analyze whether or not there is an association between variables.

Log-linear Models and Closed Form Estimates for Missing Values in Two Dimensional Contingency Tables

Cumhuriyet Science Journal
The problem of missing data is frequently encountered in scientific research due to various reasons such as nonresponse in surveys, data recording errors, data loss, or limitations inherent in the study design. Missing data mechanisms are classified into

Beyond Transconductance: Cell‐Polymer Coupling Determines Fidelity in Action Potential Recording via Electrolyte‐Gated Polymer Transistors

Advanced Science, EarlyView.
High electrical performance alone does not guarantee efficient bioelectronic signal transduction. Despite excellent mixed ionic‐electronic conduction, recordings from cardiomyocytes reveal that p(g2T‐TT)‐based OECTs predominantly transduce field potential FP‐like signals due to weak cell‐polymer coupling.
